Is it possible to know more than the experts just by looking stuff up online?

Presumably in some very specific subject matters; there's just a ridiculous fucking amount of information on the internet. But I wouldn't particularly count on it in most cases.

Experts being those who spent their lives in research of a subject or who learned by doing (like doctors)? I don't think it's possible.

"Experts" can be bought, bribed etc. Fluoride in the water is a prime example, if you follow the thread all the way to the end you discover that fluoride is toxic waste, destroys our health and if really bad. However the government needed a use for it to cover up things that happened (Manhattan Project).

If you're talking about climate change, then yes. America funded a fake climate change report using lower ranked experts. The top experts agree that pollution is at catastrophic levels. Always remember that American business is the greed driven enemy of mankind.

There's a lot of misinformation online so you have to be careful.
That being said, there's also a lot of good information as well. You need to have a good sense of knowing how to discern good sources of information from bad.

Experts process their topic better. It's not just facts.

No. Much of the information online is not correct.

Experts... you mean like the Generals?

he so-called 'experts' are motivated politically and bias findings according to that agenda. So, yes. If pursuits are undertaken without political bias the information is far more accurate.
